Rubber Diaphragms (Diaphragm Seals)

Custom Gasket Mfg. is a recognized leading manufacturer and supplier of high qualityrubber diaphragms, also referred to as diaphragm seals.Our company’s reputation for excellence has been built on our ability to provide our valued customers with the most effective designing, engineering and manufacturing solutions to meet their most demanding applications. Our main objective is to continuously exceed our customer’s expectations by providing them with high performance gaskets and sealing products, competitive pricing, on-time delivery and exceptional customer service. Custom Gasket Mfg. maintains a modern manufacturing facility along withknowledgeable, technically-oriented professionals enabling us to consistently meet all of your blueprint specifications and tolerance requirements.

Custom Gasket Mfg. has over forty years experience specializing in the manufacturing of precision molded rubber products, including fabric reinforced rubber diaphragms and homogenous (all rubber) diaphragms. By definition, rubber diaphragms are flexible seals that prevent unwanted transmission of substances between two places. These substances can be liquids, gasses or solutions. They are characteristically tough and dynamic and essential in many flow control applications. We provide full production capabilities from prototype and short run quantities through large production runs. Custom Gasket Mfg. takes pride in its ability to consistently produce precision custom rubber diaphragms guaranteed to meet your most stringent requirements and function perfectly within your application. The rubber molding tolerances for rubber diaphragms are complaint with rubber molding industry standard RMA A2 Precision tolerances.

Fabric Reinforced Rubber Diaphragms

Custom Gasket Mfg. provides a variety of custom molded fabric reinforced rubber diaphragms designed and engineered for specific industry applications, including pneumatic actuators, pumps and control valves. Our years of experience in the gasket manufacturing industry has proven that certain applications demand that a rubber elastomer layer must be very flexible and tough in order to withstand repeated flexing over a long lifetime. It is required that each and every custom molded rubber diaphragm be able to handle mandatory operating temperatures and also be resistant to any chemicals, fluids or gases it may come in contact with. The construction of fabric reinforced rubber diaphragms is achievable using special reinforcement materials including:

Polyester (Dacron)

Polyamide (Nylon, High Strength)

Cotton

High-Temp Polyamide (Nomex®)

Liquid Crystal

Polymer based fabrics (Vectran®)

Homogenous Rubber Diaphragms

Custom Gasket Mfg. provides diaphragms produced entirely of rubber. These homogeneous rubber diaphragms are used in very low-pressure applications when the strength of a fabric reinforced diaphragm is not required. Homogenous rubber diaphragms offer similar functional advantages as fabric reinforced diaphragms and tend to be more economical for our customers not requiring a sturdy construction.
